Abstract

A photocatalyst compound comprising: (i) a photocatalyst selected from the group consisting of TiO2, WO3 and mixtures thereof, the photocatalyst being substantially free of sharp, narrow band X-ray reflections at angles corresponding to those of crystalline TiO2, WO3 and mixtures thereof, and (ii) a porous, crystalline, adsorbent support material. A process for producing the photocatalyst compound is also disclosed. The process comprises: (i) hydrolysing a non-ionic titanium compound to produce a colloidal suspension having an average particle size of less than about 250 .ANG.; (ii) contacting a porous, crystalline, adsorbent support material with the colloidal suspension to produce an impregnated support; and (iii) calcining the impregnated support to produce the photocatalyst compound. The photocatalyst compound is useful, inter alia, in the treatment of a fluid containing an organic pollutant.
